Problems solved by technology

[0003] In the existing technology, the current mainstream of welding of two pipes or metal containers is manual outer wall ring welding, which especially tests the skills of welders for welds with large cuts, and it is difficult to ensure the stability of welding quality , the welding efficiency is low and the labor intensity is increased; most of the existing automatic welding equipment is aimed at the external welding of structural parts, and generally cannot perform welding on the inner wall of narrow and small pipelines. Using the model robot to crawl on the inner wall will easily lead to deviation of the route, slipping and poor weld quality

Abstract

The invention discloses a self-crawling type automatic welding device for large pipelines and containers. The self-crawling type automatic welding device comprises a welding gun, a welding gun moving mechanism, an annular rotating mechanism and a climbing mechanism. The welding gun movement mechanism comprises a rotating assembly, a feeding assembly, a lifting assembly and a moving assembly. The welding gun is connected to the rotating assembly, the rotating assembly is connected to the feeding assembly, the feeding assembly is connected to the lifting assembly, and the lifting assembly is connected to the moving assembly. The annular rotating mechanism comprises an upper sliding block and a lower sliding block; the upper sliding block and the lower sliding block are both in an arc shape, the upper sliding block is connected to the lower sliding block in a sliding mode, a telescopic magnetic piece a is connected to the outer arc face of the upper sliding block, a telescopic magnetic piece b is connected to the outer arc face of the lower sliding block, and the moving assembly is connected to the top end of the upper sliding block in a sliding mode. Automatic welding of the inner wall of a pipeline or a metal container can be completed, and time and labor are greatly saved; and during welding work, the whole device is stable and reliable, the accuracy of a welding seam is guaranteed, and then the welding quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of welding devices, in particular to a self-crawling automatic welding device for large pipelines and containers. Background technique [0002] When two pipes or two metal containers are butt welded, it mainly includes the pipe or metal container pair operation and the pipe or container welding operation; when the outer diameter of the pipe or metal container is the same, the butt welding needs to ensure that the pipe and the pipe , or the concentricity between the container and the container, it is also necessary to ensure that the internal and external stagger values ​​of the group butt weld meet the requirements of the standard. [0003] In the existing technology, the current mainstream of welding of two pipes or metal containers is manual outer wall ring welding, which especially tests the skills of welders for welds with large cuts, and it is difficult to ensure the stability of welding quality , the ...
